Hello 
i have a problem with the audio management of manjaro KDE 
The idea is to use the audio buttons( Volume up/Down) to change volume which works totally fine!
The Problem however is that if i hold down either of the buttons the volume will increase / decrease for longer than the button is held down.
Edit(seems helpful to post but missed it first):
Output from inxi -Fx:
Audio: Device-1: Intel Comet Lake PCH cAVS vendor: Lenovo driver: sof-audio-pci bus-ID: 00:1f.3
Sound Server-1: ALSA v: k5.9.16-1-MANJARO running: yes
Sound Server-2: JACK v: 0.125.0 running: no
Sound Server-3: PulseAudio v: 14.2 running: yes
Sound Server-4: PipeWire v: 0.3.26 running: no
Edit:
the xev output is ok utill the last event!
holding down the volume up key results in a iteration of:
KeyRelease event, serial 40, synthetic NO, window 0x5000001,
root 0x933, subw 0x0, time 2602261, (250,247), root:(250,276),
state 0x1c, keycode 123 (keysym 0x1008ff13, XF86AudioRaiseVolume), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
KeyPress event, serial 40, synthetic NO, window 0x5000001,
root 0x933, subw 0x0, time 2602261, (250,247), root:(250,276),
state 0x1c, keycode 123 (keysym 0x1008ff13, XF86AudioRaiseVolume), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
most times ending on a keyPress event and then the audio wont stop increasing/decreasing untill one either presses volume up or down another way to stop it is to use “xte keyup” on either volumeup or down key.
Edit:
just tested if its something with my config but the same happens on the Current Live version downloaded today.
Edit:
For now i use different keys to adjust the volume which works perfectly fine but seems off that just 2 keys are not working properly if all other keys don’t have such problems 
Best Regards
